A construction of UD $k$ -ary multi-user codes from $(2^{m} (k - 1) + 1)$ -ary codes for MAAC

SHAN Lu, Wei Hou, Jun Cheng +1

In this paper, we proposed a construction of a UD $k$ -ary $T$ -user coding scheme for MAAC. We first give a construction of $k$ -ary $T^{f + g}$ -user UD code from a $k$ -ary $T^{f}$ -use…

Construction of Unrestricted Rate Parallel Random Input Output Code

Shan Lu, Horoshi Kamabe, Jun Cheng +1

A coding scheme for two-page unrestricted-rate PRIO code that each page may have different code rates is proposed. In the second page, the code for each messages consists of two co…

Signature Design of Sparsely Spread CDMA Based on Superposed Constellation Distance Analysis

Guanghui Song, Xianbin Wang, Jun Cheng

Sparsely spread code division multiple access (SCDMA) is a non-orthogonal superposition coding scheme that permits a base station simultaneously communicates with multiple users ov…
